Do you think ICO is the best way to invest in?
Yes, it is, but look for the ICO you can trust.
1. The project should have a growth potential which depends on the relevance of the idea.
2. It is crucial that the ICO has a working product.
Such as the reOrder ICO -
https://ico.reorder.world. They already have a working product and as for the growth potential: the market of public catering will benefit from the automation, regardless whether it is growing or falling, which make this ICO very promising.
And we can't have a trust in all ico's, there are to many of them and probably just some of them will be successful in long term. Which one is big question, I invested in one casino ico, there are more then one but I chose just one. Also kick ico doesn't look bad, I didn't bought yet but I will see to get in after I see their start.
I will check out your suggestion, ico.reorder.world. sounds interesting and you described it nice, maybe there is something behind.
